Description
Technical Field
The invention relates to the technical field of hydrophobic surface treatment, in particular to a polymer product surface treatment method, a hydrophobic polymer product and application thereof.
Background
In recent years, the bionic super-hydrophobic material attracts people's extensive attention due to its surface unique performance. The surface with a static contact angle of more than 150 degrees and a rolling angle of 0-10 degrees is generally defined as a super-hydrophobic surface, and has application values in the aspects of self-cleaning, corrosion prevention, pollution prevention and the like. Inspired by the "lotus effect" of nature, researchers found that the superhydrophobicity of a surface was determined by both the chemical composition and the microstructure of the surface. Based on this, methods for structuring a superhydrophobic surface such as a plasma etching method, a chemical deposition method, a sol-gel method, an electrostatic spinning method, a template method, and the like have been proposed.
CN1760112A discloses a method for manufacturing a superhydrophobic surface with a dual microstructure, which comprises the following steps: (1) micromachining is carried out on an aluminum sheet with the purity not lower than 99.99 percent to obtain a micron-sized array on the aluminum sheet, wherein the length, the width and the height of the microcolumns in the micron-sized array and the distance between the microcolumns in the micron-sized array are 10-100 mu m; (2) preparing a nanopore array on the surface of an aluminum sheet with a micron-sized array by adopting an anodic oxidation method, wherein the depth and the aperture of each pore in the nanopore array and the distance between each pore in the nanopore array are 10-100 nm; (3) taking an aluminum sheet with a micron-scale array and a nanopore array as a template, transferring a double microstructure of the aluminum sheet to a polymer film by adopting a nano-imprinting method, preserving heat, reducing the temperature to be below the glass transition temperature of a polymer, and keeping pressure in the cooling process; (4) separating the aluminum sheet and the polymer film to obtain the super-hydrophobic surface with the double microstructures, and the method has low production efficiency, is difficult to meet the requirement of mass production and has lower practicability.
CN101851069A discloses a method for preparing a superhydrophobic surface, which comprises the following steps: (1) spreading or fixing a layer of screen made of metal wires or high-temperature-resistant plastic wires on a plane or curved-surface high-temperature-resistant substrate, wherein the meshes of the screen are 200-2500 meshes; (2) hot-pressing a hydrophobic thermoplastic polymer on the screen or hot-pressing the screen on the surface of the hydrophobic thermoplastic polymer, and controlling the hot-pressing temperature to enable the surface of the hydrophobic thermoplastic polymer to reach a viscous flow state; (3) and stripping the screen from the surface of the hydrophobic thermoplastic polymer at the temperature lower than the viscous flow temperature of the hydrophobic thermoplastic polymer to obtain the polymer super-hydrophobic surface. However, this method can only obtain a small-sized superhydrophobic surface with a simple shape, and cannot handle a complicated large-sized part (e.g., a washing machine outer tub) with an irregular curved surface.
The washing tub of the washing machine includes a washing tub, which is generally referred to as an inner tub, and a tub, which is referred to as an outer tub. Water is present in the gap between the inner tub and the inner and outer tubs in normal operation of the washing machine. The pollutants such as impurity, incrustation scale, dirt, clothing batting, detergent foam in aquatic can adhere including in clearance between the outer bucket, plastics outer bucket surface, and along with the extension of time, the pollutant is more and more, and is in semi-closed state for a long time between washing bucket and the water holding bucket, and is more moist, breeds bacterium and microorganism easily. These contaminants and microorganisms are liable to cause secondary pollution in the washing tub of the washing machine along with the water flow during the washing process.
In summary, in the prior art, the hydrophobic treatment of the polymer requires the use of expensive raw materials, special processing equipment or complex processing technology, and it is difficult to realize industrial production, so there is a need in the art to provide a simple and easy hydrophobic treatment method for polymer products.
